2. Learning ObjectivesLearning Objectives

student should be able to:
 Explain relevant concepts in joint
mobility assessment

assessment techniques

to the use of joint mobility assessment

situation, interpret the results of the
joint mobility assessment
 Record in an acceptable format the
findings gathered from the joint
mobility assessment
 Given a simulated patient care
situation, demonstrate joint mobility
assessment techniques with correct
procedure and patient care skills
 Given a simulated patient care
situation, communicate the
assessment rationale, procedure, and
results clearly and concisely

joint surfaces
amount of
joint motion
mobility and pliability
of the soft tissues

5. Amount of Joint MotionAmount of Joint Motion
shape of
articulating surfaces
health of
surrounding tissues
health of the
joint
load-deformation
history of the joint

6. physiologic motion is limited
by a physiologic barrier
tension develops within the
surrounding tissues
(joint capsule, ligaments
and connective tissue)

7. additional amount of passive
range of motion can be performed
accessory motion can be observed
• when resistance to active
motion is applied
• when the patient’s muscles are
completely relaxed
the anatomic
barrier cannot be
exceeded without
disrupting the
joints integrity

11. Assessment ProceduresAssessment Procedures
 Pain Assessment
 Active Motion Test
 Passive Motion Test (Endfeel)
 Passive Accessory Mobility Test (PAM
Test)
 Passive Accessory Intervertebral
Mobility Test (PAIVM Test)

12. Passive AccessoryPassive Accessory
Mobility TestMobility Test
 tests the accessory joint motion
 determines if joint accessory motion is
hypomobile, normal or hypermobile

13. Passive AccessoryPassive Accessory
Mobility TestMobility Test
 gives information about the integrity of
the inert structures
 accessory motion are involuntary
 muscles cannot restrict the glides of
a joint (with just a few exceptions)

14. PositioningPositioning
 avoid closed-packed positions
 use open-packed positions (resting
position)
 or place the joint at the end of
available motion (especially the spine)

15. Use of GlidesUse of Glides
 Base direction of glide on
 the direction of the limited
physiologic motion and
 the convex-concave rule

16. Use of GlidesUse of Glides
 Perform 2 to 3 glides (ideally 1 only)
 Test the unaffected extremity (or
spinal segments) first
 to provide baseline information
 to avoid traumatizing the patient

17. Use of Distraction andUse of Distraction and
CompressionCompression
 Provides additional information as to
the structure causing the problem
 Perform 2 to 3 distractions /
compressions (ideally 1 only)

18. Use of Distraction andUse of Distraction and
CompressionCompression
 Test the unaffected extremity (or
spinal segments) first
 to provide baseline information
 to avoid traumatizing the patient

19. PrecautionsPrecautions
 same as the precautions and
contraindications of PJM and spinal
mobilization

HypermobilityHypermobility
hypomobile jointhypomobile joint
lesser movement compared to what is
normal or compared to the same joint
on the opposite extremity
hypermobile jointhypermobile joint
more movement compared to what is
normal or compared to the same joint
on the opposite extremity

22. Hypomobility vs.Hypomobility vs.
HypermobilityHypermobility

functional

damage from occurring

23. HypermobilityHypermobility
generalized hypermobilitygeneralized hypermobility
multiple joint laxity; greater mobility in
all joints
e.g. acrobats, gymnasts, genetic
diseases
localized hypermobilitylocalized hypermobility
single joint involvement
reaction/compensation to neighboring
joint stiffness or injury

27. Interpreting GlidesInterpreting Glides
If the joint glide is unrestricted
 integrity of both the joint surface and
the periarticular tissue is good
 the patient’s loss of motion must be
the result of contractile tissue
 intervention: soft-tissue mobilization

28. Interpreting GlidesInterpreting Glides
If the joint glide is unrestricted and excessive
 excessive motion may indicate:
 pathological hypermobility
 instability
 may be normal for the individual
 intervention:
 stabilizing techniques to support the joint
through muscle action and
 mobilization of hypomobile neighboring joint

29. Interpreting GlidesInterpreting Glides
If joint glide is restricted
 LOM is caused by the joint surface and
periarticular tissues (but contractile
tissue may still be affected)
 intervention: joint mobilization
 once intervention is done,
osteokinematic motions are assessed
again. if movement is still limited then
the muscles are at fault

30. Interpreting DistractionInterpreting Distraction
 if distraction is limited, it may indicate
a contracture of connective tissue
 if distraction increases pain, it may
indicate a tear of connective tissue and
may be associated with increased
range
 if the distraction decreases pain, it
may indicate an involvement of the
joint surface

31. Interpreting CompressionInterpreting Compression
 if the compression increases pain, a
loose body or internal derangement of
the joint is present
 if compression decreases pain, the
joint capsule may be affected
